B
Converts excess to glycogen for storage
C
Deaminates amino acids to urea for excretion
D
Synthesises plasma proteinsThis is a wrong answer
Explanation: 

Detailed explanation-1: -In the human body, deamination takes place in the liver. It is the process by which amino acids are broken down. The amino group is removed from the amino acid and converted to ammonia. The rest of the amino acid is made up of mostly carbon and hydrogen, and is recycled or oxidized for energy.

Detailed explanation-2: -So, the correct option is ‘breakdown of cholesterol’.

Detailed explanation-3: -Thus, the correct answer is ‘Absorption of food and excess water from the undigested food. ‘

Detailed explanation-4: -It helps in the excretion of vitamins, drugs, steroid hormones, and waste material through bile. The liver converts the amino acids present in the blood into ammonia and pyruvic acid. Pyruvic acid gets oxidized to release energy, and ammonia gets converted into urea.
